To all whom it may concern: features of construction and combinations of Beit known that we, EUGENE RILEY EDSON parts hereinafter described, and pointed out and BENJAMIN F. SILLIMAN, citizens of the in the claims.

United States of America, residing at Cleve- Y In the accompanying drawings Figure l is 5 land, in the county of Cuyahoga and State of aside elevation, largely in central section, 55

Ohio, have invented certain new-and useful of a drier embodying the invention which Improvements in Driers; and We do hereby constitutes the subject-matter of this applideclare the following to be a full, clear, and cation.

exact description of' the invention, such as Ourimproved drier comprises an interiorlyro will enable others skilled in the art to which chambered jacketed cylinder composed of 6o it pertains to make and use the same. annular sections a, assembled endwise and This invention relates to improvements in horizontally arranged in line between two driers, and pertains more especially to a drier heads b, which 'close opposite ends, respeccomprising a sectional jacketed interiorlytively, of the drying-chamber formed by and I5 chambered horizontally arranged cylinder, interiorly of the said cylinder-sections. The 65 which forms the drying-chamber of the drier cylinder of the drier illustrated is therefore and is closed at its ends by suitably-applied arranged horizontally and comprises three heads. annular sections a. Each cylinder-section One object of this invention is tovrender a comprises an inner cylindrical cast-iron zo the drier long-lived and' to construct a drier vshell c, exteriorly jacketed, as will herein- 7o comprising corresponding interchangeable :after appear. Each shell c is provided at and separable jacketed annular cylinder-sec- .each end and externally with a laterally andtions assembled endwise between thev heads outwardly projecting annular iiange d. Each of the drier. Y shell c is provided exteriorly and at each 25 Another object is to provide each annular side centrally between the top and bottom 75 cylinder-section with aheating-jacket and to of the said shell with a horizontallyarform the said cylinder-section by an inner ranged flange c,which extends longitudinally annular cast-iron'shell provided at each end of the shell and connects together and braces and externally with alaterally and outwardly apart the annular end flanges d of the'shell.

3o projecting annular fiange and having two Each cylinder section a comprises also a 8c horizontal flanges arranged at opposite sides, heating-jacket, which comprises two platerespectively, ofthe said shell and formed ,metal semicylindrical sections f,which einupon and externally of the said shell'cenbrace the upper portion and lower portion,- trally between lthe top and bottom of the respectively, of the shell c of the said cylin- 3 5 shell and connecting together the end flanges der-section a. 85 of the shell, with the jacket of the said cylin- The upper jacket-section fIof each. cylinder-section made in two semicylindrical secder-section a, embraces and conforms to the tions embracing the upper portion and lower upper portion of the shell c of the said cylinportion, respectively, of the aforesaid shell der-section and rests at the bottom upon the io and flanged exteriorly along and secured to flanges e of the said cylinder-section, and the 9o the aforesaid exterior anges of the said cylsaid jacket-section fis provided at the upper inder-section and with communication besides of the said Iianges @and exteriorly with tween the interior chambers of the jackets laterally and outwardly projecting horizonof the cylinder-sections suitably established. tally-arranged lianges g, which abut against 45 Another object of this invention is to renthe upper sides of and extend longitudinally 95 der the construction simple and convenient of the said flanges c. in the assemblage and renewal of parts. The lower jacket-section fof each cylinder- With theseobjects in View and to the end section a embraces and conforms to the lower of .realizing other advantages hereinafter apportion of the shell c of the said cylinder-sec- -5o pe'aringV this-invention consists in certain tion and is arranged below the flanges e of roo the said shell. The said lower jacket-section is provided next below each flange e of the said shell with a laterally and outwardly projecting horizontally-arranged flange h, which abuts against the under side of the said flange c of the said shell.

The flanges g and 7L of the jacket-sections f of each cylinder-section a are riveted, as at la, to the flanges e of the shell c of the said cylinder-section.

Each jacket-section f of each cylinder-section ctextends snugly between the end flanges d of the shell c ot the said cylinder-section and is provided at the ends with laterally and outwardly projecting flanges Z, which abut against and extend along the said flanges (l of the said shell and are riveted to the lastmentioned flanges, as at m. Each jacket-section f is enough larger than the adjacent portion of the shell c embraced by the said jacket-section to form a chamber n between the said jacket-section and the said shell c, and communication between the two chambers n, formed next exteriorly of the upper portion and lower portion, respectively, of the said shell c by the jacket-sections f, embracing the said shell, is established by holes or ports p, formed in and extending vertically through the flanges e of the said shell between the latter and the said jacket-sections and arranged at suitable intervals longitudinally of the said Ilanges. Communication between the chambers n of adjacent cylindersections a is established by slots or ports r, formed in and extending laterally through the adjacent end flanges d of the said sections at suitable intervals circumferentially of the said sections and next to the inner sides of the jacket-sectionsfof the said cylinder-sections.

As already indicated, the cylindersections o, correspond in dimensions and construction, so that they are interchangeable, and adjacent sections a. are separably secured together by suitably-applied bolts and nuts. Adjacent langes d of adjacent cylinder-sections a beyond the outer sides of the jacketsections f of the said cylinder-sections have registering horizontally-arranged holes s extending therethrough at suitable intervals circumferentially of the said cylindersections and engaged by bolts t, and correspondingly-threaded nuts u are mounted upon the screw-threaded Shanks of the said bolts, and the arrangement of the parts is such that the said cylinder-sections a have their said flan ges clamped together by and between each boltt and the nut u upon the said bolt. It will be observed, therefore, that adjacent cylindersections a are separably clamped together.

The shell c of each cylinder-section a is provided with a pipe connection w, arranged centrally between the ends of the said shell and centrally between the flanges e of the said shell, which pipe connection has its interior passage-way com municating with the interior chamber of the said shell and extends through the adjacent jacket-section f of the said cylluder-section, which jacket-section is suitably apertured, as at as, to accommodate the location of the said pipe connection and secured to the said shell at suitable intervals around the said pipe connection by screws y.

As already indicated, one of the jacket-sections f of each cylinder-section a. surrounds the pipe connection w of the said cylindersection, Whereas the other jacket-section f of the said cylinder-section is provided diametrically opposite the aforesaid pipe connection w with a comparatively diametrically smaller pipe connection fu, whose interior passage- Way communicates with the chamber n, formed next interiorly of the last-mentioned jacket-section.

By the construction hereinbefore described it will be observed that upon loosening the nuts u instrumental in clamping adjacent cylinder-sections a together each of the said sections is rendered free to be turned independently of the other of the said sections, and hence the cylinder-sections are adj ustablc circumferentially.

In Fig. 1 the arrangement of the parts is such that the pipe connections w of the outer cylinder-sections a are at the top of the drier and the pipe connections o of the jackets of the said cylinder-sections are at the bottom, whereas the pipe connection w of the central cylinder-section a is at the bottom and the pipe connection u of the jacket of the lastmentioned cylinder section is at the top. Consequently in the drier illustrated the pipe connection w of the central cylinder-section a forms the material-discharging outlet ofthe drying-chamber of the drier, through which outlet material is removed from within the said chamber, whereas the pipe connection w of each outercylinder-section 0L forms acharging-aperture and vapor-outlet, through which the said chamber is supplied with material to be dried or heated within the said chamber and which accommodates the escape of vapors and gases from the said chamber. lt will be observed also that the pipe connection v ofthe central cylinder-section a in Fig. l forms the steam-inlet of the jacket of the drier, whereas the pipe connections c of the outer cylinder-sections a constitute the drain passage-ways of the said jacket.

The upper portions of the shells c of the cylinder-sections a because of their greater exposure to iron-corroding vapors and gases arising from material treated within the drying-chamber become Worn more rapidly than the lower portions of the said shells, and consequently the importance of the circumferential ad justability of the cylinder-sections a is obvious. When, therefore, the upper portions of the shell c of the cylinder-sections a become worn to such an extent that a readjustment of the said sections is deemed advisable, the nuts u are loosened to accommodate the said readjustment, whereupon the cylinder sections a are turned halfway IOO IOS
